Conclusion

By considering the needs for water supply to different cities at the downstream of the East River (150m³/s) and waste assimilative capacity (267m³/s), the minimum flow for water sustainability in the East River is 417 m³/s.  However the percentage of days with streamflow exceeding 417 m³/s is only 60%, reflecting the threat of water sustainability in the East River Basin.

The water challenges can be met through integrated river management – including emphasis of reservoir operation on flood control and water supply, provision of effective wastewater treatment, and water and soil conservation.
